What planet have these guys been on

An engineer with Shell Canada has come up with a way to use a by-product from the oilsands of Alberta to create large utility-scale electricity storage for renewable energy projects.
Steenkamp has constructed his vanadium redox flow battery inside a garden shed, powered by solar panels on top of the research center. He has been running the battery through continuous cycles of charging fully, then draining completely - recording data to gauge its performance.

So far, the battery can only hold a charge of six-kilowatt hours, enough to run a hairdryer for about four hours. Obviously, it would need to be much larger to store energy from a wind or solar farm, but Steenkamp says it can be scaled up. "If successful, it could be an absolute game changer. It will prove that we are capable of delivering renewable energy game-changing ideas not in spite of traditional energy but precisely because of it.," said Steenkamp.

Meanwhile in China

"This factory produces vanadium redox-flow batteries destined for the world’s largest battery site: a 200-megawatt, 800-megawatt-hour storage station in China’s Liaoning province."
